Calendar from MacBook, crash frequently, then not syncing to other devices
Since I upgraded to Catalina, Calendar on my MacBook keeps crashing, and/or I have to Force Quit. And now, I notice that nothing I've added to Calendar via the MacBook is making it to any of my other devices. This includes anything in my iCloud calendars, various Exchange calendars, etc. This also includes any Invitees that I've added, NOTHING is going out. I've tried signing in/out of all Accounts, nothing is working. Any ideas?
